Explanation:
Detailed explanation-1: -Answer and Explanation: The compound with equal hydroxyl and hydrogen ions is pure water.
Detailed explanation-2: -Reading the pH scale It indicates the concentration of hydrogen ions (H+) and hydroxide ions (OH-) in a solution. These ion concentrations are equal in pure water, which has a pH of 7.
Detailed explanation-3: -Any aqueous solution in which [H+]=[OH−] is said to be neutral. For any neutral solution at 25oC, each of these ions has a concentration of 1.0×10−7M.
Detailed explanation-4: -At pH 7, the substance or solution is at neutral and means that the concentration of H+ and OH-ion is the same.
Detailed explanation-5: -A neutral solution contains equal amounts of H+ or OH-ions.
